The side of the air exchange box is connected to an air inlet pipe, and a first valve is installed on the air inlet pipe. Two partition plates are fixedly connected inside the air exchange box, dividing the air exchange box into two layers. One of the partition plates has a connecting pipe on its lower surface, and a second valve is installed on the connecting pipe. An electric telescopic rod is fixedly connected to the top surface of the air exchange box. A fan is fixedly connected to the output end of the electric telescopic rod. The side of the fan is slidably connected to the inner wall of the air exchange box, which facilitates the switching between suction and blowing modes by a single fan, providing a more comfortable experience for the driver.

[0007] According to the aforementioned automotive seat ventilation and airflow guiding device, a connecting pipe is fixedly connected to the side of the air exchange box, and one end of the connecting pipe is connected to the upper layer of the air exchange box, so that air can be conveniently transported to the inside of the main conveying pipe through the connecting pipe.

[0008] According to the aforementioned automotive seat ventilation and airflow guiding device, the end of the connecting pipe away from the air exchange box is connected to the main conveying pipe, and the upper surface of the main conveying pipe is connected to multiple secondary conveying pipes, so as to facilitate the conveying of air through the main conveying pipe and the secondary conveying pipes.

[0009] According to the aforementioned car seat ventilation and airflow guiding device, a plurality of first ventilation pipes are fixedly connected to the inner bottom surface of the seat cushion, and a plurality of first branch pipes are connected to the upper surface of the plurality of first ventilation pipes. The upper end of the first branch pipes extends to the outside of the seat cushion, and airflow is facilitated through the first ventilation pipes and the first branch pipes.

[0010] According to the aforementioned car seat ventilation and airflow guiding device, a plurality of second ventilation pipes are fixedly connected to the inner side wall of the backrest, and a plurality of second branch pipes are connected to the sides of the plurality of second ventilation pipes. The end of the second branch pipe away from the second ventilation pipe extends to the outside of the backrest, and airflow is conveniently achieved through the second ventilation pipes and the second branch pipes.

[0011] According to the aforementioned car seat ventilation and airflow guiding device, two adjacent first ventilation pipes are connected by a pipe, and two adjacent second ventilation pipes are connected by a pipe. A flexible hose is connected between the side of the first ventilation pipe at the right end and the side of the second ventilation pipe at the lower end to facilitate the connection between the first ventilation pipes and the second ventilation pipes.

[0012] According to the aforementioned automotive seat ventilation and airflow guiding device, an exhaust pipe is fixedly connected to the side of the air exchange box, and one end of the exhaust pipe is connected to the lower layer of the air exchange box to facilitate gas discharge.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] The sliding rod moves the insertion rod, which easily releases the insertion rod's restriction on the mounting frame. The spring elasticity makes it easy to push the insertion rod into the mounting frame, which facilitates the restriction, disassembly of the filter screen and mounting frame, and replacement or cleaning of the filter screen.

[0015] By opening the first valve on the intake pipe, air intake is facilitated. By starting the fan, air is encouraged to flow out from inside the connecting pipe, facilitating air blowing. The electric telescopic rod extends and retracts, allowing the fan to move downwards. By closing the first valve and simultaneously opening the second valve, the upper and lower layers of the air exchange box can be connected via the connecting pipe. Then, the fan is started to facilitate air intake. The ability to switch between intake and blowing modes using a single fan provides a more comfortable experience for the driver.

Airflow is delivered via the connecting pipe 16, main conveying pipe 11, and secondary conveying pipe 12, and then dissipates heat through the first ventilation pipe 10 and the first branch pipe 9. The connecting hose 13 connects the first ventilation pipe 10 and the second ventilation pipe 14 for comprehensive airflow. When the temperature reaches a comfortable level, the system can be switched to suction mode. The controller extends the electric telescopic rod 18, causing the fan 25 to move downwards. Then, the first valve 21 is closed, and the second valve 23 is opened, switching between suction and blowing modes for a more comfortable experience. The filter 5 absorbs dust from the air entering the mounting box 3. When the filter 5 needs to be removed, the sliding rod 6 moves the insertion rod 7, releasing the restriction on the mounting frame 4, making it easy for staff to remove the filter 5 and the mounting frame 4. During installation, the spring 8 pushes the insertion rod 7 into the mounting frame 4, completing the restriction and facilitating the installation and removal of the filter 5.
